What happen with the your mobile? Did the LCD broken or no display? Before you have it fix, do this basics check: Do the phone power on? When there is a sim card inserted, can you call the phone or can it place a call? Do the phone rings when called. Do you hear sounds from speakers?

LCD or display cost approximately QR 1,500 to 1,800 including parts and professional fee. Depends with the source of the replacement parts.
